 '''Summary of the bug:'''
 The .sfd (Sofdec Dreamcast Movie) fails to properly interpret audio
 streams starting at 0x1c1. FFMpeg reports that address, but it can't do
 anything with the audio. This format has been used in literally thousands
 of older games. FFMPEG is able to properly handle audios streams that
 start at 0x1c0, but not c1. The file isn't broken, this was taken from an
 Xbox game and these files play properly on that platform.

 '''How to reproduce:'''
 {{{
